Schematic representation of the Method.1a An individual was considered as “could not be reached” if the individual with a working number was called at least 3 times and was unreachable after a minimum of three attempts or if the person was unable to respond because of persistent healthcare issues and was receiving ongoing care in a medical facility.1b Miscellaneous reasons for exclusion were: Patients who were deceased during the call period of May 6th–June 30th 2020, patients who were screened for SARS-CoV-2 prior to procedures (childbirth, surgeries, etc.), had no symptoms indicative for COVID-19 and tested negative, and those who could not remember getting tested were excluded from the study.1c COVID- 19 positive patients were defined as either patients who tested SARS-CoV-2-positive (N = 435), or as patients who tested negative but presented with COVID-19-like symptoms and met clinical criteria for probable COVID-19 illness as determined by the treating physicians (N = 51).
